This involves four different implementation strategies: 1. For Windows, we now require _configthreadlocale() to be available and work (commit f1da075d9a0), and the documentation says that the object returned by localeconv() is in thread-local memory. 2. For glibc, we translate to nl_langinfo_l() calls, because it offers the same information that way as an extension, and that API is thread-safe. 3. For macOS/*BSD, use localeconv_l(), which is thread-safe. 4. For everything else, use uselocale() to set the locale for the thread, and use a big ugly lock to defend against the returned object being concurrently clobbered. In practice this currently means only Solaris. The new call is used in pg_locale.c, replacing calls to setlocale() and localeconv().
